1 kilowatt of solar PV in Arizona produces an average of 1,720 kilowatt-hours of electricity per year, so a 8.0 kilowatt solar system would generate 13,757 kilowatt-hours of electricity every year. An average household in Arizona uses 12,333 kilowatt-hours of electricity in a year.

With an average state electricity price of 13 cents per kilowatt-hour, this solar system could save a household in Arizona $1,757 each year.
